The minimization of the makespan of a printed circuit board assembly process is a complex problem. Decisions involved in this problem concern the specification of the order in which components are to be placed on the board, and the assignment of component types to the feeder slots of the placement machine. If some component types are assigned to multiple feeder slots, then the additional problem emerges of selecting, for each placement on the board, the feeder slot from which the related component type is to be retrieved. In this paper, we consider this Component Retrieval Problem for placement machines that operate in a similar way as the Fuji CP II. We explain why a simple forward dynamic programming scheme cannot provide an efficient solution to this problem, thereby invalidating the correctness of an earlier published approach. We then present a polynomial algorithm that solves the problem to optimality. The analysis of the Component Retrieval Problem is greatly facilitated by its reformulation as a longest path problem in a PERT/CPM network with design aspects. Finding the minimal makespan of the assembly process thus amounts to identifying a design for which the longest path in the induced network is shortest. As an alternative interpretation, the Component Retrieval Problem can be viewed as a shortest path problem with side-constraints. The complexity of these network problems is analysed, and it is proven that the polynomial solvability of the Component Retrieval Problem is caused by the specific structure it inflicts on the arc lengths in the network. In the absence of this structure, the network problems are shown to be NP- hard in general. [less ▲]

We investigated the aerial parts of Haplophyllum pedicellatum collected in the district of Samarkand (Uzbekistan). We have separated and identified 11 components, of which 7 compounds including the alkaloids acetylevoxine, glycoperine and glucohaplopine, all three isolated lignans (suchilactone, diphyllin and justicidin B) and the flavonoid glycoside ( limocitrin 7-O-beta-glucoside) were observed for the first time in the aerial part of H. pedicellatum.The structures were established by comparison with standars and with spectral data. the cytotoxic activity was determined : the flavonoid exhibited a moderate activity.

Les études cliniques sur les couronnes et les bridges en zircone Y-TZP ont indiqué des taux d'échecs élevés liés aux fractures cohésives de la céramique d’émaillage (chipping). Pour remédier à ce problème, les fabricants commercialisent des couronnes monolithiques, entièrement en zircone, qui sont simplement maquillées en surface. Cependant, ces restaurations sont suspectées d’être plus sensibles à la fatigue hydrique de la zircone, problème qui aboutit à une baisse des propriétés mécaniques et qui fut à l’origine de nombreux échecs avec les prothèses de hanche. En effet, l’absence de céramique d’émaillage sur les couronnes monolithiques les rend plus vulnérables vis à vis du milieu oral ; de plus, certaines zircones de haute translucidité, spécifiquement développées pour cette indication, sont réputées plus sensibles en raison d’une plus grande métastabilité. Enfin, le recul clinique sur ces restaurations est très faible et leur comportement général, notamment en terme d’usure des dents antagonistes, a besoin d’être étudié. Une étude clinique est actuellement menée à l’Université de Liège, en collaboration avec l’Université Paris Descartes, afin d’évaluer le comportement clinique de la zircone non émaillée en milieu buccal, et particulièrement la fatigue hydrique, sur une période de 5 ans. Les résultats à très court terme (6 mois) mettent en évidence le bon comportement clinique des restaurations monolithiques en zircone, avec cependant une usure rapide de la glaçure, ce qui pourrait promouvoir la fatigue hydrique. Les zones de transformation cristalline détectées soulignent la nécessité d’une cuisson de régénération de la zircone suite aux ajustements occlusaux par fraisage. [less ▲]

His female was meanwhile brooding a second clutch. This cluth has been raised by a foster-father (an unknown adult male) whereas the female started a third clutch. [less ▲]

Au printemps, la Meuse en aval du barrage de Visé-Lixhe (fig. 1) est un important lieu d'alimentation des hérons cendrés vraisemblablement attachés à la héronnière de Lanaye (une cinquantaine de couples reproducteurs en 2004; voir Annexe 1) située en aval et à celle de Vivegnis située en amont (Jacobs et al., 2003). Par ailleurs, le site de Lixhe offre des conditions d'observation exceptionnelles pour réaliser une étude détaillée du comportement de prédation de l'espèce. C'est ce type d'étude qui a été entreprise au printemps 2004 avec un double objectif: d'une part, améliorer les connaissances sur la biologie du héron cendré dans nos régions, notamment en terme d'écologie comportementale (répertoire des comportements alimentaires, relations prédateurs-proies, incidence sur le peuplement en poissons) et, d'autre part, tester une méthodologie d'étude transposable à des sites comparables et spécialement à des piscicultures.

In expertise context, the psychological or psychiatric assessment occurs in a particular and different way than the usual practice in psychotherapy. In this context, malingering has a specific dimension that we study in this article. As the domain of malingering is very huge, our article focuses on situations ofdamages compensations. After a definition of malingering, we analyse this behaviour through the study of the victimology process, the circle influence, the existent psychological tests and the expert’s role. The victim position in which the injured persons are placed or place their self seems to be a factor involved in their reconstruction process and by thisway, in the use of malingering. The family circle has also a strong influence on the management of the traumatic incident and by this way, on the (conscious or unconscious) choice of malingering, particularly for children (by example, in the Munchausen by proxy syndrome). Finally, the role and the attitude of the expert are central in the functioning and the interaction of the two mechanisms (management of the event/reconstruction by the victim and malingering). Although psychological tests can be used in order to discover malingering, a meticulous assessment, empathy, and neutral and benevolent attention are indispensable elements in order to respect the suffering of the person and by this way, assure authentic complaints and thus prevent malingering.
